SPECIFICATION forming part of Letters Patent 0. 599,614, dated February 22, 1898. Application filed May 5, 1897. lSerial No. 685,197. (No model.)

To all whom it may concern:

Beit known that I, J OHN O. KORN, a citizen of the United States, residing at Wilkes- Barr, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Flask, of which the following is a speci fication.

My invention relates to flasks for use in casting; and the object in view is to provide [0 a device adapted to be constructed as an attachment for application to flasks of the ordinary construction, whereby the cope and drag may be readily connected and disconnected in the operation of molding without the use of bolts and similar devices heretofore employed.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out. in the appended claims.

In the drawings, Figure 1 is a perspective view of a flask provided with a fastening device constructed in accordance with my invention.

of one end of the flask, showing the fastening device. Fig. 3 is a detail view in perspective of the fastening device detached.

Fig. 4 is a-detail view of the locking-lever de- 0 tached.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlngs.

1 designates a cope, and 2 the drag, of a flask of the ordinary construction, the former being provided with depending pins 3, held in place by securing-plates 4., and the latter being provided with sockets 5 for the reception of said pins, the sockets being formed in The pins are shouldered, as shown at 7, and when the members of the flask are connected said shoulder is located just below the plane of the lower surface of the flange 6 in position for en- 5 gagement by the beveled face 8 of a button or locking-lever 9. The shoulder 7 is preferably inclined to cooperate with the beveled surface of the button or locking-lever, whereby when the members of the flask have been connected it is simply necessary to press the locking-lever to place manually. There is no Fig. 2 is a vertical central sectionnecessity to employ a hammer or other means for attaining the desired relative positions of the parts. Hence the connection and disconnection of the members of the flask may be accomplished without loss of time and without danger of breaking the apparatus.

The button or locking-lever 9 may be pivotally mounted upon the flange 6 by any suitable means, such as'a pivot-pin 9 In practice I propose to construct the device separate from the flask, whereby it may be applied to old flasks now in use and which are not provided with flanges or handles; but where the flask members are provided with handles they may be adapted for the fastening device embodying my invention by providing the same with openings for the reception of the pins. The cope is also provided with flanges 10, having openings 11, whereby a plurality of flask -sections may be tiered and connected by a chain extending through the openings in the flanges 10 to facilitate elevating a number of said parts simultaneously. Thus the cope handles or flanges are useful not only as means whereby the flasksection may be readily manipulated in applying and removing it, but also in connecting a plurality of such sections when used simultaneously.

Inasmuch as no jarring or hammering of the flask is necessary in order to engageor disengage the members thereof, there is no liability of shifting or crushing or jarring any of the hanging sand from the cope or allowing metal to flow out on the joint. The engagement of the cam locking-levers is firm and efficient when they are adjusted or forced to place solely by the pressure of the fingers of the operator. 0

An important feature of the construction above disclosed and one which is of special advantage in connection with flasks is that the cam-faced locking device by which the shouldered pin of one member of the flask is engaged is permanently mounted upon the other member of the flask, whereby it is always in position for use.

Such changes in the form, proportion, and the minor details of construction as fall within the scope of the claims may be resorted to without departing from the spirit or sacriin the perforation of said flange or handle, said cope being further provided near its upper edge with a perforated flange or handle, and abevel-faced cam-lever pivoted upon the flange or handle of the drag for engaging the shoulder of the pin on the cope, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
